Had this happen to me before more than once, a bottle of red armor didn't have enough oil and made my weed eater stall.
But the first time it happened it was my fault I accidentally used enough oil to make 2 gallons problem was I was using a 2.5 gallon tank, didn't realize it was a 2.5 gallon tank not my gas can and I didn't fill it and my buddy told me it was 2 gallons.... Very dumb I should have looked.
Few years later I dumped in a bottle of "1 gallon oil mix" into my usual 1 gallon gas can, filled up my ran dry weed eater and when I started it, my faithful weed eater didn't want to stay running. Knew I had seen this before.
So I opened my last "1 gallon mix bottle" and just dumped a little more oil straight into the weed eater, ran great. Dumped the rest of that gallon of 2 stroke gas into my truck and started measuring the 2 stroke my self from then on.
That was last bottle of 2 stroke mix from that pack, so I didn't have more to measure and my next purchase was a refillable squeeze bottle of red armor.
According to the video it looks like pre-measured bottles sometimes come up 4 to 10cc short maybe more in my case.
I still use pre-measured bottles occasionally, I use ones that are somewhat translucent to light and that I filled. I mark where the oil should be with a sharpie so I can check it before I dump it. As these pre-measured "1 gallon mix bottles" stay in my saw box and get knocked around and may leak a few drops over time since they aren't factory sealed anymore. Plus I run 40:1 in the saws and I can't buy pre-measured red armor in 40:1 for mixing up 1 gallon of gasoline at a time.
What the amsoil lacks in actual product volume may be intentional since they claim leaner mixes work fine. Whatever they may lack in product volume they more than make up for with hiberus.
